drive S120 sinamics PAR1135 e PAR1121

[matrix1967]

Good morning everyone, a question regarding a 1PH8 motor controlled by a Sinamics S120 drive... I wanted to know the difference between the PAR1135 (OFF3) and the PAR1121 (OFF1), the par1135 in theory intervenes with a drive or motor fault if it disengages from the correct control? While the par1121 intervenes until the OFF1 is at threshold 0 and then makes its ramp... but these two parameters must be set to the usual value? Because usually we calculate the value for the par1135 taking into account the maximum revolutions on par1082, the roller diameter and the transmission ratio... once this time has been calculated, the usual value is set on the par1121, is this correct? If the drive does not have the ramp generator enabled r108.8, what ramp does it follow? That of the master?
